SECTION 1 

SAFETY PRECAUTIONS 

Product Safety Notice 

For the continued safe operation of this monitor, it is imperative 
that the components shown in the shaded areas of the various 
electrical schematics included in this manual be replaced only 
with those specified in the manual's parts lists. The use of 
substitute replacement parts that do not have the same safety 
characteristics as those specified may create shock, fire 
X-radiation and other hazards. 

A" other electrical or mechanical parts must be replaced by those 
.ving identical specifications as determined from the parts lists. 
Potentiometers must be resealed with approved sealant after service 
adjustment or replacement. Under no circumstances may the original 
design be modified or altered without written permission from 
Philips Electronics Ltd., 601 Milner Avenue, Scarborough, Ontatio. 
M1B 1M8. 

X-Radiation Warning 

When replacing the CRT or any other components in this monitor, use 
only a designated replacement part present on the bill of material. 
Many components are "safety critical components" and must be replaced 
with approved parts to ensure this monitor will comply with the 
safety agencies X-ray emission limits. 

Personal Safety Precautions 

Notice: Observe all cautions and safety related notes located inside 
the monitor chassis and on the CRT. 

WARNING 

1. Operation of this monitor with the rear cover and safety screens 
removed can expose the operator to a shock hazard. Only 
qualified service personnel should attempt to repair this 
monitor. Service personnel must read all the following 
precautions before starting repairs on this monitor. 

I. The following safety precautions must be observed when working 
on this monitor: 

a) To reduce the possibility of an electric shock or burn, remove 
all rings, wristwatches, braclets, necklaces and other jewelry 
before attempting to repair this monitor. 

b) Before reaching inside the monitor to remove modules or cable 
assemblies, always turn off the AC power switch and disconnect 
the AC line cord from the back of the monitor. 






SERVICE MANUAL 
MODEL: M19P114P/7103 



r ART NO. 

5107 991 05491

c) The CRT should always be discharged before reaching into the 
monitor. The flyback transformer in this monitor has an 
internal bleeder resistor that will discharge the CRT after 
the AC power is removed. But if this resistor should fail, 
the anode will remain charged at 20kY. 

If the anode connector is removed from the CRT during repairs, 
the CRT should again be discharged before reassembly as a 
charge can build up on the CRT anode during the repair time. 

d) The AC line cord that is included with this monitor has a 
safety ground and must always be connected to a ground out- 
let. Never use an adaptor plug to connect the monitor's 
three-prong AC power plug to a two-prong wall outlet. 

a) Never use a grounding wriststrap, heelstrap or work on a 
grounded workbench when discharging the CRT or when per- 
forming adjustments on an operating monitor. These ground 
straps should only be worn when working on modules outside 
of the monitor. 

f) When handling the CRT, eye protection should always be worn. 
The CRT should always be carried. with two hands firmly holding 
the CRT face plate and metal rim band. Never pick up or 
handle the CRT by its neck. The CRT in this monitor weighs 
approximately 11.4kg. 

Safety Check-Out 

Before the- Atari Monochrome Monitor is returned to the customer 
after servicing, both the following safety. checks are required: 

Hi-Pot Test 

.he Hi-Pot test is performed to check the insulation resistance 
between the AC line terminals of the input and chassis ground. 

Equipment Required: 

1) Hi-Pot tester, R00-L M100 or equivalent. 

Procedure: 

NOTE: The high voltage must be increased and decreased gradually 

during the test. The ramp-up and ramp-down rate must be 

set to 500 volts/second maximum. 

1) Unplug the Atari Monochrome Monitor from the AC mains. 

2) Turn the ON/OFF switch to J the "ON" position. 

3) Plug the AC line cord from the Atari Monochrome Monitor into the 
Hi-Pot tester. 

4) Connect the "Chassis Ground" clamp off the Hi-Pot tester to 
the chassis of the monitor.

5) Turn on the Hi-Pot tester. 

6) The green pilot "ready" light must be illuminated otherwise 
the grounding connection between the monitor and the Hi-Pot 
tester is not properly done. 

7) Press the "Start" button on the Hi-Pot Tester. " The Orange 
"Testing" light must be illuminated. The monitor must be 
tested at a maximum Hi-Pot Tester. The Orange "Testing" 
light must be illuminated. The monitor must be tested at a 
maximum Hi-Pot voltage of 1500Vrms for 1 to 2 seconds. The 
maximum leakage current allowed during this test is 10mA. 

8) If the red "fault" light comes on during the test, there may 
be a fault with the monitor. The test can be repeated after 
a 10 second wait. If the red fault light comes on again, the 
monitor must be repaired as there is a problem with the 
insulation between the AC line terminals and chassis ground. 

9) Turn off the Hi-Pot tester. 

10) Unplug the monitor from the Hi-Pot tester. 

11) Disconnect the "Chassis Ground" clamp from the chassis. 
Ground Continuity Test 

Equipment Required: 

1) An AC source capable of 12 Vac maximum (open circuited) and 
25 Amps continuous current (current limited) with a built-in 
Ammeter. 

2) A Digital Volt Meter (DVM) if the AC source does not have a 
built-in voltmeter. 

Procedure: 

1) Connect the AC source between these two contact points: 

a) The ground pin of the AC input connector. 

b) The- ground shell of the input signal connector. 

2) Turn the supply on. 

3) Measure and record the voltage drop between these two 
points on the DVM. 

4) Measure and record the current flowing between the two 
contact points. 

5) Turn off the AC source.

6) Calculate the resistance between the two contact. points. 
It must not exceed 0.1 ohms. 

7) Repeat the above test with the AC source connected between: 

a) The ground pin of the AC input connector. ■ 

b) The chassis of the monitor. 

The calculated resistance must not exceed 0.1 ohms. 



NOTE: 



If either of the tests indicate a resistance of over 
0.1 ohms, the monitor fails the Ground Continuity test 
and must "be repaired. The most likely fault is a 
disconnected or loose wire between the video board or 
the EMI line filter and the grounding stud on the rear 
panel. Also check that the grounding stud is securely 
mounted and all lock nuts on the stud are tight.

.3 Pretest Verification 

Prior to proceeding, verify the following conditions. Any units 
tailing this stage must be returned for repair. 

Vert. Freq: With the unit unsynchronized, connect a frequency counter 
to TP302, and adjust R335 for a reading of 65Hz +2/-lHz. 

Connect the signal and select the all black pattern. 
EHT to be measured 20kV ±1.3kV. 

Select all white pattern, connect voltmeter to IC201 
Pin 6, and adjust R230 for a reading of 6.5VDC. 

3 Raster Centering: Horizontal 

Pre-adjust brightness to approximately 15FL with raster visible. 
Video must be centered in raster (R229) such that left hand visible 
raster is equal to or 2mm larger than right hand visible raster (see 
Mg. 4.3.1.4). The width control may be adjusted to bring the raster 
edges just within the bezel opening.

Start with circular magnets (centering magnets) in neutral position 
i.e. slotted ear of one magnet aligned with plain ear of other 
magnet, both positioned so that th ears are in the horizontal 
position of raster. Adjust magnets simultaneously and in opposite 
directions so as to avoid bending horizontal lines and centering 
active image within bezel gauge, (see Fig. 4.3.1.6). 

Raster Centering; Vertical 

Adjust vertical position of center line with vertical position 

control R333. 

This should center horizontally and vertically a cross hair target 
pattern such that center lines are within the target windows of Fig. 
4.3.1.6 The vertical center line shall be at 90° ±0.5 to the horizontal 
center line within a 2" radius of screen center. 

4.3.1.5 Linearity and S-Correction 

a) With a cross-hatch pattern applied adjust R312 (overall Vert. Lin), 
R333 (vertical shift) and R329 (Height) to obtain uniform block sizes 
and active video centered in bezel gauge. 

The width (L202) and horizontal linearity (L203) coils are 
interactive. L203 should first be adjusted to obtain maximum width, 
then turned slowly from that position until 
picture is the same size as the right half, 
the correct width, and verify that the left 
remain of equal size. Slight adjustment of 



the left half of the 
Adjust L202 to obtain 
and right picture halves 
the width control will 



not require readjustment of the lenearity coil. 

b) Adjust L205 (H.F. S correction) to obtain smallest 3-rd hormonic 
horizontal linearity distortion. Default position of L205 is such 
that Y = 6.0 Y DD (measured during active video time only - see 



picture). 



NOTE: Please do not exceed Y=10V p p when setting L205.

NOTE: The adjustment must be done introducing the slug of L205 into 
the coilform from the preset position. 

L205 may require re-adjustment to obtain best linearity, and 
test point 1 voltage could then be anywhere between 3 - 10Y. 

c) Verify the horizontal raster centering as in Paragraph 4.3.1.4. 
4.3.1.5 Video Size and Geometry 

a) Make iterative adjustments as per 4.3.1.4 and 4.3.1 5 in order to get 
the video pattern within the limits of the bezel gauge. Using 
Crosshatch, approximately 1" squares, pattern vertical and horizontal 
block sizes must not differ by more than 7% calculated as follows: 



FOR ANY TWO BOXES: 

-0.07 < 2(W1 - W2) ± .07 
Wl + W2 

AND 

-0.07 1 2(H1 - H2) < .07 
HI -I- H2 



b) All edges of the active video area shall fall inside of the limits of 
the bezel gauge, including the effects of geometric distortions as 
pincushion, barrre>, trapezoid, parallelogram and raster rotation. 

The raster shape and orientation shall not be objectionable due to 
wavy edges, apparent rotation etc. 

Raster rotation not to excede 3mm as measured vertically on a center 
horizontal line of the display area.

4.3.1.7 Brightness Adjustment 

Important Note: 

During the adjustment procedure please be careful not to touch black 

level preset R633. (This control has been already adjusted at board 

level). 

1. Apply signal, reverse video pattern. (White screen) 

2. External Brightness Control R415 to detent. 

3. Adjust R607 (Maximum Contrast Preset ) to achieve 36V pp video 
swing at CRT cathode. 

4. Adjust Brightness Preset R410 for 21. ± 3 FL at the centre of the 
CRT. 

5. External Brightness Control R415 to maximum. 

6. Adjust R416 (Maximum Brightness Preset) for 35 ±5 FL at the centre 
of the screen. 

7. Brightness Control Action: Observe the screen while adjusting the 
Brightness Control to ensure smooth, continous action of the control 



NOTE: Since the video output is set at 36YP-P, this places the raster far 
into cut-off and under no signal conditions, the raster may not be 
visible, even when the external brightness control is adjusted to 
maximum. If necessary R410 Brightness Preset can be adjusted in 
order to increase the brightness so that the raster is just visible. 
If the brightness is set too high the EHT overcurrent sensing circuit 
will switch power supply off.

THEORY OF OPERATION 



8.1 Main Board 



The main board hosts circuitry for the off-line SMPS, horizontal 
and vertical deflection, flyback transformer, CRT bias, dynamic 
focus circuitry, and safety circuit to prevent X-ray emission. 

8.1.1 Power Supply 

8.1.1.1 Summary 

Operating from a power line of 90 - 264 VAC, the switch supply 
delivers a power of 50 Watts into five D.C. outputs. 

The power supply consists of the following building blocks. 

* A.C. Line Filter 

* A.C. Line Bridge Rectifier and Smoothing Capacitor 

* Isolated D.C. to D.C. Buck-Boost Converter 

* Control Circuitry: 

- Pulse Width Modulator (PWM) 

- Voltage Feedback 

- Over Voltage Protection 
-Horizontal D'efl. Sync. Circuit 

8.1.1.2 Line Filter . 

The line filter is necessary to limit the conducted electro- 
magnetic interference to the A.C. power source. The filter 
components are enclosed in a metal case, together with the 
IEC Power Connector and the ON/OFF Switch. This assembly is 
mounted onto the chassis rear panel with two screws. 

8.1.1.3 Line Bridge Rectifier and. Smoothing Capacitor 

Diodes CR10S - 109 form a bridge rectifier. Capacitor C101 
smoothes out the rectified voltage to a D.C. value plus a 
2 x Line Frequency Ripple Voltage. When the A.C. supply 
vanes from 90 - 264 VAC, the voltage across C101 varies 
from 100 - 400V.

The converter operates in the discontinuous current mode. 
It is a three state circuit: first the switch Q102 is 
turned on, second Q102 is off and CR160 conducts, and 
third, neither Q102 or CR160 conducts. For any value of 
input voltage of load condition the circuit always cycles 
through these three states. 

8.1.1.4 Control Circuitry 

The control circuitry consists of four elements. The Pulse 
Width Modulator (PWM), Voltage Feedback Network, Over 
Voltage Protection, and Horizontal Deflection Synchronizing 
Circuit. 

8'.1. 1.4.1 Pulse Width Modulator 

The PWM is implemented using the UC3842AN (IC130), which is 
a current mode control Ter by Unitrode. The output of IC130 
at pin 6, remains ON until the current sensed by pin 3 
reaches a set value. The current level in the primary of 
T101 is determined by the value of resistor R106 and the 
set point at pin 3. This constitutes the inner current 
loop of the converter. 

8.1.1.4.2 Voltage Feedback 

The voltage feedback determines how much current in the 
primary is necessary to produce the desired output voltage 
of 82.0Volts @ 450mA. The transformer T101 is designed to 
produce the following auxiliary voltages: 

+58V @ 200mA 

+27V 8 300mA 

+12Y 8 200mA 

-6.3V 8 330mA 

The voltage loop consists of a voltage divider R164, R165, 
and R166, that feeds a shunt regulator, IC163 (TL431). The 
shunt regulator adjusts its output voltage (at the Cathode) 
to obtain a fixed 2.50Y at its input (the reference). 
Using R162, a current is developed in the diode part of the 
Optocoupler IC131 which is reflected to the transistor 
section. The current flowing; into R131 creates a D.C. 
voltage whose value controls the magnitude of the primary 
current, and consequently set the output voltage. This 
system constitutes the outer voltage feedback loop.

Q207 provides a current souce. The value of the current is 
proportional to the free running frequency and adjusted by 
R230. 

R229 provides a current offset at the opamp input. That 
input remains at a constant DC voltage and since there is 
no other DC feedback path the way the PLL circuit can com- 
pensate the offset is to shift the phase of its generator 
to provide a pulse of an appropriate width at the phase 
detector output. That pulse is converted into current by 
R231 and an equlibrium is reached. By means of adjustment 
of R229 the offset current is changed and so is the 
horizontal phase. 

Q201 and Q202 are used in order to delay start-up. The PLL 
will not start until sufficient power supply voltage is 
reached in order for VCO to be able to generate the right 
frequency. This way an overload condition during power-up 
is eliminated. 

8.1.2.3 Driver and power stage, horizontal output. 

A small power MOSFET Q205 is used in the driver stage. 
Driver Transformer T201 is employed in order to obtain 
proper base current during the on state of the horizontal 
output transformer Q206. When the driver transistor 
switches on 0206 switches off initiating horizontal retrace. 
The flyback transformer is. used to provide EHT as well as 
voltages for Gl, G2, and the focus circuit.

Should the limit for the EHT/anode current combination be 
exceeded the shutdown signal is sent to the power supply. Power 
will have to be disconnected for a while to allow the latch to 
reset. (Approximately 30 seconds - see Power Supply). 

Notej. The following components are critical for safety of the 
monitor user and should only be replaced by the original 
types: T202, CR702, R705, CR702, IC701, R702, R703, R704,

8.1.3 Vertical Deflection. 

Vertical deflection provides a sawthooth current waveform in the 
vertical coils of the deflection yoke to effect vertical 
displacement of the electron beam. The vertical circuit is 
built around the TDA2S53A. Specifically the following features 
are worth mentioning: 

8.1.3.1 Vertical Linearity 

Vertical linearity compensation is achieved by distorting the 
nAnt^t ^ at pin U us ing Positive feedback from pin 3 
(IC3Q1) to the junction of capacitors C313 and C314 

8.1.3.2 Vertical Shift 

Q303, Q304 and IC501-C provide a circuit for vertical shift. 

The circuit can source and sink current from IC301 output via 
the vertical deflection coil. By adjusting this current the 
??n ?!! ? f , the raster can be ad Justed on the face of the CRT. 
nil Ul I°2u S aS a current source from the coil side it does 
not affect the linearity. 

8.1.3.3 Vertical Retrace 

Q302 is used to shorten the retrace time. 

8.1.3.4 Crosstalk 

Vertical crosstalk filter L301 is implemented to reduce 
crosstalk and ringing occuring because of the interaction 
of the horizontal 4 vertical deflection coils.

8.1.4 Focus 

The focus circuitry provides a complex waveform voltage to the 
G4 electrode of the CRT. This focus voltage waveform consists 
of a D.C. component, a parabolic waveform component at the 
vertical frequency, and a sinusoidal waveform component at the 
horizontal frequency. The amplitude of the horizontal component 
is modulated by a papabolic waveform at the vertical frequency. 

Main circuit blocks: 

- Vertical sawtooth waveform integrator IC-501-B 

- Modulator IC501-D 

- Horizontal component output stage Q502. 

- Vertical -component output stage Q503, IC501-A 

- Horizontal component transformer T501 

- Static focus circuit Q505 

8*1.4.1 Vertical Component: 

A sawtooth waveform across current sensing resistor R323 is 
integrated by IC501-B. The resulting parabola is then 
amplified by the vertical component output stage and 
coupled through R538 to G4. 

8.1.4.2 Horizontal Component: 

The horizontal frequency component of the focus waveform is 
generated by applying short duration, low voltage pulses 
across the primary of transformer T501. Due to step-up 
design of this transformer, the peak secondary voltage is 
much larger than the primary voltage. The pulses excite 
the parallel resonant circuit formed by. the secondary of 
T501 and capacitors-C506 and C507. The inductance of T501 
is adjusted such that the horizontal foucus waveform is in 
phase with horizontal deflection.

8.1.4.3 Modulation. 

The vertical parabola is also used to modulate the 
horizontal component. To accomplish that the vertical 
parabola waveform is fed to IC501-D and is added to the DC 
component at Q501 output. The vertical component causes 
the amplitude of the horizontal component to vary, 
dependant on the position of the beam on the screen face. 
The amplitude is higher towards the top and bottom of the 
screen, such that the voltage is higher in the corners than 
at the sides. The amount of modulation is adjustable. 

8.1.4.4 Static Focus

8.1.5 Brightness Adjustment Circuit. 

This Gl control circuit provides independent adjustment of 
the external brightness control 9 detent position (R410 
brightness preset), and of the external brightness control 
range (R416 maximum brightness preset). This feature 
permits precise adjustment of the maximum user brightness 
control without affecting the raster cutoff setting at the 
brightness control detent position. 

This circuitry also provides three blanking functions: 
vertical retrace blanking, spot kill on power down, and 
blanking 1n the event of vertical deflection failure. 

Major 31ocks: - retrace blanking and spot killer Q401, Q404

8.1.5 Brightness Adjustment Circuit. Cont'd 

The Q402 circuit detects the presence of the vertical 
retrace. 



Under normal operating conditions, the sawtooth current that 
flows through the vertical coils of the deflection yoke 
produce a retrace voltage. This retrace signal is detected 
by the diodes CR401 and CR402, and fed through zener diode 
VR401 to the base of Q402, which is turned on. This 
switches on the current sources Q405 and Q403, and also 
Q404. Transistor Q404 feeds the input of the differential 
amp, Q406 and Q407, with a voltage value determined by the 
position of the brightness preset pot, R410. The 
differential amp begins to stabilize that value at the 
junction of the resistor network R409, R408, and R413. 
Resistors R409 and R408 are parallel to the user brightness 
control R415. The current flowing through that network 
determines the voltage drop across the user control pot, 
and so the amount of Gl, and thus brightness, variation 
achievable by the user pot. This current is adjusted by 
maximum brightness preset R416, 

In the event that R415 is disconnected, R413 will provide 
Gl bias. 

8.1.5.1 Adjustments 

R410 - brightness preset; user control at detent position 
R416 - maximum brightness preset; user control at maximum 
position.

,2 Video Board 



8.2.1 General 



This video amplifier is based on a hybrid device for the 
output stage and a two quadrant multiplier preamplifier 
with D.C. gain control. Gated D.C. restoration triggered 
by the horizontal retrace pulse is applied during 
horizontal blanking. 

8.2.2 Preamplifier 

The balanced ECL video signal is applied to the input of 
the ECL .to TTL converter IC601 through connector J602. 

Resistors R601//R603 and R602//R604 provide the proper 
input impedance for the video signal. 

CR601, CR602, CR603, CR604 are protection diodes. 

Transistor Q601 is an emitter follower and supplies the 
positive power supply voltage for IC601. Variable 
resistor R607 changes the voltage applied to the base of 
Q601 and in consequence the B+ applied to pin 12 of IC601. 

Since the output voltage of IC601 is proportional to the 
B+ voltage applied to IC601, variable resistor R607 
controls the gain of the preamplifier. ; 

R607 is adjusted to obtain 36 volts peak to peak at the 
output of IC602 when a white ECL video signal is applied 
to the input of the video amplifier. 

The output of the preamplifier is AC coupled through 
C607 to the base of the emitter follower Q602. 

The emitter of Q602 is connected to the negative input 
of the hybrid output stage IC602. The high frequency 
network R625, C627, C628 optimizes the frequency response 
of the output stage to obtain a flat output with a minimum 
overshoot at high frequencies.

Since the video signal passes through coupling capacitors 
in the preamplifier stages, the DC level information is 
lost. A DC restoration circuit is necessary to maintain a 
constant black level at the output of the video- amp! if ier 
for any type of input signal. 

In order to maintain the output stage operating within its 
linear range, the black level is set approximately 10 Volts 
below the power supply B+. In this case, the black level 
is preset at 48 Volts DC by adjusting the variable resistor 
R633. 



Transistors Q603 and Q604 are part of the DC restoration 
circuitry. 



With 
a DC 



no signal, the output of the video amplifier should be 
level which coincides with the black level of the video 

signal and this level depends on the bias point of 

transistor Q602. 



Let us consider first a situation where no signal is 
applied at the input of the video amplifier, and the two 
extreme conditions expressed under (a) and (b) below. 



a) 



b) 



If transistor Q603 is OFF, the current through R620, 
R621 is high enough to bias the emitter of Q602 at a 
high level. Since IC602 is an inverting amplifier, a 
high level at the input would cause the DC output of the 
video amplifier to be very close to ground potential. 



DC transistor Q603 is in saturation, its collector 
voltage would be at ground potential, the emitter 
voltage of Q602 at approximately -0.7 Volts and the 
put of the video amplifier very close to the power 
supply level.

SHEET 44 OF yg 



Under normal operating conditions, none of the above 
conditions exist because the negative feedback loop keeps 
the black level at the preset value within 2%. 

In order to maintain the black level constant, a sample of 
the video output is taken from the divider consisting of 
R631, CR602, R632 and R633. This signal is then applied to 
the transistor Q604, operating as an inverting amplifier. 




ig the horizontal 

.se of transistor Q603 

ng the blanking 



.uring the horizontal blanking interval the collector 
voltage of Q604 (cathode of CR601) is around ground 
potential. Since, emitter of Q603 is also at ground 
potential, the current through R628 due to the clamping 
pulse during blanking interval will be circulating either 
to the base of Q603 or through the diode CR605 depending 
on the collector voltage of Q604. 

NOTE: Base-Emitter voltage versus current characteristics 
of Q603 and diode CR605 are very similar. 

During blanking , if the output of the video amplifier 
reduces, the collector voltage of Q604 increases, the 
voltage across diode CR605 reduces and all the current from 
the clamping pulse is then applied to the base of Q603. 
Under this conditiocr, the collector voltage of Q603 
reduces, changing the bias of the video amplifier and 
increasing the output voltage to its nominal value 
(remember that the hybrid amplifier is an inverting 
amplifier). 

Vice versa if the output of the video amplifier increases, 
the collector voltage of Q604 will be below- ground 
potential, the diode CR605 forward bias increases and all 
the clamping pulse current flows through this diode turning 
transistor Q603 OFF and allowing the bias of Q602 to rise, 
causing the output of the video amplifier to fall. 

Since this action is repeated line by line during the 
blanking time, the black level is maintained within a very 
narrow margin. 

Capacitor C518 stores the energy to maintain the proper 
bias during the scanning interval when the clamping circuit 
is inactive. 

Diode CR608 compensates for the base-emitter temperature 
variation of Q604.

8.2.4 High Frequency Adjustment 

The high frequency compensation capacitor C627 has to be 
adjusted in order to obtain a flat response with a re- 
sonable overshoot over the entire range of operating 
frequencies. 

The following procedure is recommended. 

a) Apply a white signal 0.714 Yolts peak to peak with no 
more than 2 nsec. rise and fall times, when connected to 
the input of the video amplifier. 

b) Connect a FET probe with no more than 1.5 picofarads 
capacitance to the cathode of the CRT. (Recommended 
probe, Tek. P6202A). Ground lead must be very short in 
order to avoid ringing. (If the CRT is not connected 
add an external capacitor of 6pF.) 

c) Adjust the internal gain control R607 to obtain 36Vpp 
at the output of the video amplifier. 

d) Adjust variable capacitor C627 to obtain a flat 
frequency response with no more than 8% overshoot. 

e) Verify the duration of the overshoot less than 6 nsec. 
according to the following figure:

Another possible procedure for adjusting- this high 
frequency compensation without using an oscilloscope is to 
use the monitor itself, displaying a cross-hatch test 
pattern of black vertical 1-ines over white background and 
looking at the ringing after each transition from black to 
white it is possible to adjust the high frequency 
compensation visually until the ringing disappears.
